Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment for construction engineering, in particular to a fixing device for horizontal drilling on a slope surface. Background Art

[0002] In municipal engineering and water conservancy projects, precast blocks or cast-in-place concrete slope protection are often used. However, in order to ensure that water can be drained in time after rain or immersion, horizontal holes are often drilled on the slope surface. Generally, the drilling equipment can only drill vertical holes on the precast blocks in advance, and it is impossible to ensure that the drain holes are horizontal after paving. If the horizontal drilling can be carried out after the inclined surface paving is completed, the drainage effect will be greatly improved.

[0003] The drilling device generally selects a common core drilling device, which is generally held perpendicular to the drilling surface for drilling. Therefore, a platform that can remain horizontal on the slope surface and can fix the drilling device is needed, so that the requirement of horizontal drilling on the slope surface can be realized. At the same time, it is preferably able to adjust the angle to ensure applicability to slope surfaces with different slopes. Summary of the Utility Model

A driving member connected to the self-locking transmission member is provided on one side of the base.

[0006] Optionally, through holes communicating with the inner cavity are opened at the diagonal corners of the lower side of the base.

A diagonal brace 4 connected to the limit frame 3 is installed on the horizontal plate 2. A drilling machine 7 is installed on the limit frame 3. The stability of the limit frame 3 is increased by the diagonal brace 4.

[0027] Among them, a plurality of bolt holes are opened on the base 1. A lead screw is provided at the end of the rotating shaft 6. A threaded sleeve is in threaded fit with the lead screw. An anti-slip gasket corresponding to the threaded sleeve is provided on one side of the threaded sleeve.

[0028] As Figure 1 shown, a spirit level 8 is provided on the upper side of the horizontal plate 2 in this embodiment.

[0029] One application aspect of this embodiment is as follows: First, fix the bolt holes on the base 1 by driving bolts to ensure the stability of the base 1. Rotate the horizontal plate 2 up and down through the rotating shaft 6 to adjust the level of the device, and use the spirit level 8 for detection to ensure the level of the device. Then, tighten the threaded sleeve on the screw rod at the end of the rotating shaft 6. The threaded sleeve moves through the screw rod and abuts against the anti-slip gasket to achieve angle fixation and ensure the level of the base 1. Then, place the drilling machine 7 horizontally on the horizontal plate 2 and fix the front end of the drilling machine 7 to the limiting frame 3, and then horizontal drilling can be carried out. It should be noted that all electrical equipment involved in this application can be powered by a storage battery or an external power supply.

[0030] Through the rotating shaft 6 provided on the limiting sleeve 5, when the base 1 needs to be adjusted according to different slopes, by rotating the rotating shaft 6, the angle between the base 1 and the horizontal plate 2 can be driven to change, realizing horizontal adjustment with multiple different slope rates, so as to achieve the effect of horizontally fixing the drilling machine 7 on the slope surface.

[0031] In order to reduce the time-consuming and laborious situation of driving bolts into the bolt holes respectively to fix the base 1 on the slope surface as described above, an embodiment is provided.

[0032] Embodiment Two:

[0033] Please refer to Figures 1 - 5 As shown, in this embodiment, a fixing device for horizontal drilling on a slope surface is provided, including: a base 1, a limiting sleeve 5 is installed on the upper side of the base 1, a rotating shaft 6 is rotatably fitted in the limiting sleeve 5, a horizontal plate 2 is installed on the circumference of the rotating shaft 6, a limiting frame 3 is installed on the horizontal plate 2, a diagonal brace 4 connected to the limiting frame 3 is installed on the horizontal plate 2, and a drilling machine 7 is installed on the limiting frame 3.

[0035] Through the four spiral telescopic limit members 10 provided at the bottom of the base 1, the driving member 19 can drive the four spiral telescopic limit members 10 to drill into the slope surface simultaneously through the self-locking transmission member 18, and can fix the base 1 and the drilling machine 7 on the slope surface, thus facilitating the drilling machine 7 to drill on the slope surface.

[0036] As Figure 3 shown, through holes 11 communicating with the inner cavity 12 are respectively provided at the diagonal corners of the lower side of the base 1 in this embodiment.

[0037] As Figures 3 - 5As shown in the figure, specifically, the specific structure of the spiral telescopic limiting member 10 is as follows: a rotating rod 1001 rotatably fitted in the inner cavity 12, a spiral drill bit 1002 slidably fitted at the lower end of the rotating rod 1001, a threaded sleeve 1003 installed inside the through hole 11, and the spiral drill bit 1002 is threadedly fitted inside the threaded sleeve 1003; a chute 13 is provided at the lower end of the rotating rod 1001, and a slider 14 fixedly connected to the upper end of the spiral drill bit 1002 is slidably fitted in the chute 13; first synchronous toothed wheels 15 are installed on the circumferences of the four rotating rods 1001 and are located in the inner cavity 12, and a synchronous toothed belt 16 in transmission cooperation with the self-locking transmission member 18 is sleeved on the circumferences of the four first synchronous toothed wheels 15; a connecting rod 20 rotatably fitted in the inner cavity 12 and connected to the self-locking transmission member 18 is provided in the inner cavity 12, and a second synchronous toothed wheel 17 meshing with the inner side of the synchronous toothed belt 16 is installed on the circumference of the connecting rod 20; the self-locking transmission member 18 includes a worm gear 1801 installed on the circumference of the connecting rod 20 and a worm 1802 rotatably fitted on one side of the inner cavity 12 and meshing with the worm gear 1801, and a driving member 19 is installed at the end of the worm 1802 passing through the base 1. Among them, the driving member 19 can be a rotary handle or a motor.

[0038] When it is necessary to fix the drilling machine 7 on the slope surface of the base 1, rotate the handle or start the motor to drive the worm 1802 to rotate. The rotation of the worm 1802 drives the worm gear 1801 to rotate. The rotation of the worm gear 1801 drives the connecting rod 20 to rotate.
